  • Portability of the thiolation domain in recombinant pyoverdine non-ribosomal peptide synthetases.

    abstract:BACKGROUND:Non-ribosomal peptide synthetase (NRPS) enzymes govern the assembly of amino acids and related monomers into peptide-like natural products. A key goal of the field is to develop methods to effective recombine NRPS domains or modules, and thereby generate modified or entirely novel products. We previously sho...

  • A ferritin-like protein with antioxidant activity in Ureaplasma urealyticum.

    abstract:BACKGROUND:Ureaplasma urealyticum is a major pathogen associated with many diseases. The ability of U. urealyticum to protect itself from oxidative stress is likely to be important for its pathogenesis and survival, but its oxidative stress tolerance mechanisms remain unclear. This study investigates the antioxidant ac...
